Laser pulses with stable electric field waveforms establish the opportunity to achieve coherent control on attosecond time scales. We present experimental and theoretical results on the steering of electronic motion in a multielectron system. A very high degree of light-waveform control over the directional emission of C(+) and O(+) fragments from the dissociative ionization of CO was observed. Ab initio based model calculations reveal contributions to the control related to the ionization and laser-induced population transfer between excited electronic states of CO(+) during dissociation.
具有稳定电场波形的激光脉冲为在阿秒时间尺度上实现相干控制创造了机会。我们展示了关于多电子系统中电子运动操控的实验和理论结果。观察到对从CO的解离电离中C(+)和O(+)碎片的定向发射具有非常高程度的光波波形控制。基于从头算的模型计算揭示了在解离过程中与CO(+)激发电子态之间的电离和激光诱导的布居转移相关的控制贡献。
